I hate to say this, but thanks for finally getting me off my ass to do this!
When I first got my motor from Dre, that was one of my priorities on the to do list before installing the motor. I read multiple posts about the TB problem. Well needless to say the TB screws were too damn tight and I was to scared I was going to strip the screws on my effort! I also thought maybe this is really an isolated issue and it won't/can't happen to me since the screws won't even budge! So I gave up on worrying about it and went ahead installed the motor without any loctite on my TB screws.
Fast forward about 6 months and about 4,000 miles of driving, I read your post last week and decide to try this again..just maybe it could possibly happen to me. After pulling my car out of daily service and getting it ready for my first (high performance drivers ed). Today 8/15/09 you wouldn't believe what I discover:
1 very loose TB screw and the other TB screw just turns out freely without any effort whatsoever! You saved me big time or I would have been the next to post the damage about TB screws!
Moral of story for anybody without secured TB screws: Loctite/secure your TB screws or you will be next!!
